Abstract
This invention relates to a novel two-stage dry ice system for preserving perishable items during transport and methods thereof. The improved two-stage dry ice system includes dry ice and a phase change material specifically configured within a single and continuous holding volume with perishable items. Preservation of the perishable items for extended durations in comparison to other refrigeration techniques can be achieved as a result of the two-stage dry system having the ability to re-orient itself during transport.
